For cast iron, as before, stable demand remains and many different parts and items are made from it. Iron casting - http://metalyt.com/uslugi-litya/lite-chuguna/ - here you can find quality services for this profile, we recommend that you familiarize yourself with the more detailed information on the company's website.
As a rule, cast iron is used for the manufacture of heavy and massive metal parts and structures, which are characterized by strength and wear resistance. For example, a case for gear motors, parts for units and mechanisms, benches for the garden, elements that are used in construction, etc.
The most popular and practical way is casting iron or mold. The design of the chill mold is a collapsible form, which after each pouring must be disassembled in order to release the cast-iron billet, which has hardened.
Pros
Collapsible chill molds belong to the most affordable and common method. For its manufacture, you can use sand, clay, earth or cement. In this connection, this cast iron casting technology is used in different regions where foundries and metal processing plants are located. It is worth noting that you can make a primitive chill mold even at home.
Its advantages include:
- - high quality;
- - precision casting;
- - high performance;
- - safety;
- - reasonable price.
In order to obtain blanks that will have precise shapes and holes, it is necessary to apply high-pressure casting. In this case, the molten metal will literally be pressed into all the cracks and recesses of the mold, which will thus allow to obtain a blank that will maximally meet the requirements and drawings.
This method can be used to cast ingots for the serial production of parts and accessories. It is worth noting the high price of injection molding and the fact that it requires sophisticated equipment and is not available to all enterprises.
Care
The quality of the final billet is affected not only by the alloy and temperature conditions, but also by the form itself. In the case when the chill mold is in slag or in cracks, this will significantly reduce the quality of the pig. Therefore, before pouring the mold, it is necessary to carefully examine it for cracks and whether foreign objects and impurities are present. Next, you need to remove the old paint, grease, slag, scale, any dirt that can get into the liquid metal.
After you clean the chill mold, it is necessary to assemble it, then install the rod and begin the pouring process using a specially made hole. As a rule, chillies are installed on a conveyor in a factory, and they move past a ladle with molten cast iron. Sometimes the molds may be stationary, and instead of the conveyor, the bucket will move.
Thus, the modern technology of casting iron for the manufacture of various parts has practically remained the same, but as before, it is in demand and relevant. Cast iron retains its position, and the fact that new materials and technologies have appeared has not changed this situation. Demand for it remains stable in many countries.
